HDB flooring installation: Ensuring proper subfloor preparation

Proper subfloor preparation ensures a level, clean, and dry surface, which is crucial for the longevity and stability of your new flooring. It prevents issues like unevenness, squeaking, and moisture damage.

Key steps include removing existing flooring, cleaning the subfloor, leveling any imperfections, repairing cracks or damages, and ensuring the subfloor is dry and free of debris.

For minor unevenness, self-leveling compounds can be used. For more significant issues, grinding or patching with concrete may be necessary to create a smooth surface.

Thoroughly sweep and vacuum the subfloor to remove dust, dirt, and debris. For stubborn residue, a mild detergent and water solution can be used, ensuring the subfloor is completely dry afterward.

Use a moisture meter to measure the moisture content of the subfloor. Alternatively, tape a plastic sheet to the subfloor for 24-48 hours; if condensation forms underneath, the subfloor is too damp.

Skipping subfloor preparation can lead to flooring failure, including uneven surfaces, squeaking, cracking, and potential mold growth due to trapped moisture. It can also void warranties on your new flooring.

Yes, different flooring types have specific requirements. For example, vinyl flooring requires a perfectly smooth subfloor, while laminate flooring may benefit from an underlayment for added cushioning and moisture protection. Always follow the manufacturers guidelines.
